Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed December 7, 1917. Serial No. 205,938.

My invention relates to warp-piled fabrics of the double plush class which, when separated, form two textures which are alike.

The peculiar arrangement of the pile threads in accordance with my invention not only produces pile facings of uniform density for the respective textures, but efi'ects a more general interlocking of those threads with the backing threads, than in ordinary fabrics of said class, and, consequently, renders my improved fabric more firm and durable than such ordinary fabrics.

Moreover, in such ordinary fabrics the ground threads are so arranged as to form plain cloth backs for said textures; whereas,

. the ground threads in my fabric may be arranged, a hereinafter described, to form backing cloths for the respective textures, which are twilled, to render them more pliable than plain cloth, for furniture coverings and draperies.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings: Figure I is a diagrammatic plan view of one pattern block of a double fabric embodying my invention; looking downward upon the back of the upper texture shown in Fig. II.

Fig. II is a diagrammatic longitudinal sectional view of the single texture, the back of which is shown in Fig. I; taken on the line II-II in that figure, to show the relatively staggered course of a pair of ground war threads.

Fig. III is a plan view looking downward on the back of the upper texture shown in Fig. IV.-

Fig. IV is a longitudinal edge view of said pattern block of the double fabr c, showing the general course of the warp pile threads.

Fig. V is a diagram indicating the order of shedding of both the ground and ile threads of said fabric.

In Figs. I and III, the horizontal rows of squares represent warp ends and the vertical rows of squares represent picks of weft. Accordingly, in Fig. V, the horizontal lines represent warp ends and the vertical lines represent successive shedding operations;

and the order in which'therespective warp ends are drawn up in the sheddingoperations represented by Fig. V is indicated by the 1narks at the junctions of the lines in said figure.

The fabric illustrated is conveniently made with four backing ends and four pile ends in one dent; and with six backing heddles and six pile heddles, shedded in the order indicated in Fig. V; wherein the horizontal lines 1 to 6 inclusive indicate six warp ground threads, and the horizontal lines 8 to 13 inclusive indicate six warp pile threads. Said threads are thu identified in the other figures, which show patterns each including twelve pile threads, which may be repeated transversely with respect to the respective fabrics, to any desired width.

It may be observed that said pattern of twelve pile threads illustrated includes three series of said threads, each including two pairs of pile threads shedded alike, but unlike the ad Oining series; but that, in the pattern of Figs. I to IV inclusive, said pile threads are divided in groups of four, trans versely with respect to thefabric, whereas, in the pattern disclosed and specifically claimed in my copending application Serial 238,626, filed May 10, 1918, as a division of this case; said pile threads are divided in groups of two, transversely with respect to the fabric, by respective groups of ground threads.

In the patterns of I to V; the groups 15 of said warp ground threads 1 to 6 extend only between said pile thread pairs which are shedded alike; so that each such group of four pile threads, extending between two such groups of warp ground threads, includes two pairs of said 'pile threads, 8 to 13, which are shedded unlike.

Said warp ground threads, 1 to 6, bind the.

weft threads 16 and 17 which are respectively ultimately included in the upper and lower textures formed by cutting the double fabric on the line III--III in Fig. IV; and it may be observed that said pile threads are interlocked with said ground threads so as to produce textureshaving the maximum of. firmness and consequent durability when out and separated as above contemplated. In that pattern, shown in Figs. I' V; I"

prefer to arrange the ground warp threads 1n groups 15, each consisting of four threads, divided in pairs to the re spective textures, the members of which pairs, instead of being simultaneously,- shedded up and down respectively; are

shedded successively, in relatively staggered relation? to each other, and-in a two up-and= one: down; manner with reference to the backs of? the textures; However, I do: not desire tolimit myself to the specific arrangementof the ground threads.

. In the form of my invention illustrated; the warpathreads are shedded ina reclinlng twill iuthebacksof the respective textures;v

thus affordinga desirable degree of pliabil ity, despite the firmness of the fabrics. However-,1 as they present a corresponding twilled effect: in the respective pile facings formed by; cutting said double fabrics be tween: their backing textures, in is to be notedthat-the twillis more visible in the modifications may be made therein without departing, from i the essential features thereof, asdefined: in the appended: claims;
